' Improvements in Cinder-Arresters, of which the following is a specification.

The invention relates to cinder arresters, and more particularly to the class of cinder escape attachments for locomotives.

The primary object of the invention is the provision of a cinder escape wherein all cinders on leavingthe smoke stackof a locomotive will be trapped, and thereafter conveyed beneath the boiler of said locomotive for the deposit of said cinders onto the.

. bed of a track, thus obviating the possibility of such cinders and sparks flying through the air rearwardly of the train when traveling or at a standstill.-

Another object of the invention is the provision of a cinder escape wherein the cinders from the smoke stack are arrested prior to the deposit on the bed of the track, the cinders also being cooled before the discharge thereof onto the track bed.

A further object of the invention is the provision of a cinder escape which is simple in construction, novel in form, reliable and eflicient in operation, and inexpensive in manufacture.

With these and other objectsin view, the invention consists in the construction, com bination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereunto appended.

In the drawings :Figure 1 is a side elevation of a locomotive, showing the cinder escape attachment constructed in accordance with the invention applied thereto. Fig. 2 is a front elevation of the same. Fig. 3 is a vertical longitudinal sectional view. Fig. 4 is a perspective view of the battle cone support. Fig. 5 is a sectional view on the line 55 of Fig. 3.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings in detail, A designates generally a locomotive, which is of any ordinary well-known construction, having the usual smoke stack 15, through which the smoke and cinders from the firebox are discharged in the usual manner, and suitably supported upon this locomotive is the cinder escape attachment hereinafter fully described.

The cinder escape attachment comprises a cylindrical drum 10, preferably made from sheet metal, and is arranged concentrically about. the smoke stack B, the drum being of greater height than the said smoke stack and is fixed to the boiler of thelocomotive in any desirable manner. This drum 10 is designed to serve as a trap for all cinders and sparks emitted from the smoke stack B of the locomotive, the cinders and sparks being arrested therein in a manner presently described.

Arranged within the smoke stack B is an adjustable support comprising a central collar 11, an adjustable ring 12 concentric thereto, and adjustable spokes 13 which are joined to the collar 11 and ring 12 respectively in any suitable manner, the said spokes being arranged radially from the collar toward the ring. The adjustability of the support permits it to be mounted within different sizes of smoke stacks. Fitted within the collar 11 is the apex 14c of an inverted conical shaped baffle head or cap 15 which is adapted to deflect the cinders and sparks from the smoke stack B laterally against the wall of the drum 10 so that said cinders and sparks will drop into the same and be prevented from discharging through the free end or open mouth of the drum, the circumferential wider end of the head or can 15 being of greater size than the circumference of the mouth of the smoke stack B so as to properly deflect the cinders and sparks leaving the latter into the drum. Connected to the larger end of the head or cap 15 at the periphery thereof are brace arms 16, the same being arranged radially at equidistances apart and are secured to the wall of the drum so as to hold the head or cap rigid and in proper position within the drum.

At the forward or front side of the drum 10 is a horizontally directed elongated opening 17, the same being covered by means of a wire mesh screen 18, and through which is admitted cold air to the interior of the drum 10 for the cooling of the cinders or sparks delivered thereto.

Communicating with the drum 10 at diametrically opposite points thereof are rear- ;wardly inclined conveyer tubes or pipes 19,

he same being disposed at opposite sides of the boiler of the locomotive A and are con;

in any suitable manner, and through these tubes or pipes 19 communication between the drum 10 and cylinder'21is had so that the cinders from the said drum will be conveyed through the tubes 19 into the cylinder for a purpose presently "described. i Arranged within the cylinder 21 is a spiral way 22 to feed the cinders'from the tonof' the cylinder 21 to and into a delivery spout 23 leading from the lower end of the said cylinder 21 in a direction 'rearwardly I of the locomotive, the discharge end of the 21 onto the track bed 24 through the spout spout being disposed at the desired elevation above the bed 24 of the track 25011 which the locomotive A travels so that thecinders will be deposited from the cylinder 23 between the rails of the track.

1 In the use of the cinder escape it will be clearly apparent that the cinders and sparks will be arrested after leaving the smoke stack B of the locomotive A, and thereafter cooled prior to the delivery of the same from the escape onto the bed 24gbetween the rails of the track 25, and in this manner the said cinders or sparks will be pre- I vented from flying through theair rearwardly of the locomotive.

I and a From the foregoingit is thought that the construction and manner of operation of the device will be'clearly understood, and therefore a more extended explanation has been omitted.

What is claimed is p y. I

A cinderv escape for locomotives comprising'a cylindrical drum of a greater size'than and adapted to be concentrically secured about the smoke stack'of the locomotive *and having a wire 's'creened aperture in the front thereof near the lower end of the same, a spider supported within the stack, an inverte'd "substantiallyconical shaped head carried by th'esupport and having its wider end disposed above the outerend of the stack, braces extending from the wider end 'of the head to thedrumpa cylinder arranged beneath the boiler of the locomotive rear v v wardly with respect to the stack, a conveyer p'i peleading from the drumne'ar its lower end and opening through the top of'the cylinder a'spiral baffle-within the cylinder,

discharge spout leadingfrom the bottom of'the cylinder andhavin gvits free end directed ,rearwardly of the locomotive.

In testimony whereof I aifix my signature in presence of two witnesses.
